Answer» Answer: food is important. Explanation: 1. food provides nutrients. nutrients provide energy for body activities and all functions of the body. energy is used of a living organism in different PROCESSES like breathing , DIGESTING food, etc. 2. Plants do breathe - they give out carbon dioxide and absorb oxygen from the air that surrounds them. Their tissues respire just as animal tissues do. Plants, however, do not have lungs or a BLOOD stream, so we cannot say that they breathe in the same way as animals. 3.Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or ASEXUAL reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from the parent or PARENTS. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur.
